Abstract

A moving image distribution system, wherein the user can view content moving images at no charge, and the provider of the content moving images can prevent a drain of the moving image contents and can protect the copy right thereof, as a copy right holder, without fail. The moving images are divided, along a time axis, into two master and slave non-reproducible moving image files. The slave moving image file (small file) is encrypted based on CM file data in which a predetermined CM element has been incorporated. In response to a reproduction request of a user terminal (5) that possesses the master moving image file (main file) in advance, the slave moving image file is distributed with the CM moving images to the user terminal via a network line such as the Internet.
